I have not tested it yet but I plan to within the next weeks. Looks like we have to investigate how to use the new prio keyword with Intel’s dual storage controllers. I this won’t work, maybe we can still use the old dm-multipath that worked nicely. I will let you know when I have finished testing XenServer 6.2 on IMS

Just for information, looks like XS6.1 has device-mapper-multipath 0.4.7 and XS 6.2 has device-mapper-multipath 0.4.9. In latter the prio_callout keyword has been deprecated. I will try and install the old verson on XS 6.2

1. Reverted back to 6.1 driver, using multipath.conf that came with 6.1 driver. Same result.
2. Installed 6.2 driver, modified multipath.conf to remove prio_callout and replaced with: prio “aula” without a positive effect.

Yes, the package you provide just needs to be updated with the mulipath.conf that I provided. I’ve been throwing a ton of I/O at the disk array and zero issues. I would like confirmation of the fix by another person. I even recomplied the driver and got the same size rpm. I think it all works.

Nice. My IMS server is being used in production and I don’t risk to pull out any of the storage modules to test at the moment. I can only test XS 6.2 on one of the modules without pull out test. Did you do the pull test too, preferably several times on different storage modules?
